Specification of Letters Patent. Application filed December s, 1912. Serial. No. 737,115.

It) ([55 'tU/LOHZ it may concern:

Be it known" that I, Connan A. JOHNSON, a citizen of the United States, residing at- Jamestown, in the county of Chautauqua,

State of New York, have invented certain use the same.

T his invention relates to windows and has for an object to provide a sheet metal windowsash having novel lneans'for securing a screen or a window pane without the ,use of screws, nails, putty or similar devices.

A further object of the invention is to provide a sash h ring a spring locking strip which when applied will secure the screen or window pane tightly in place, and which may be easily manually removed to permit withdrawal of the screen or pane.

Vv ith the above objects in view the invention consists of certain novel details of con-' struction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended-claims.

In the; accompanying drawings forming part ofthis specification:-Figure 1 is a front elevation of a screen embodying my improvements. Fig. 2 is a cross sectional View taken on the line 2-2 Fig. 1. Fig. 3

is a cross sectional view taken on the line 3-3 Fi g. 1. Fig. i is a view similar to Fig.

. 3 showing a pane of glass substituted for the screen. Fig. 5 is a fragmentary perspective view of one rail of the sash. Fig. 6 is a fragmentary perspective view of the abutment rib. Fig. 7 is a fragmentary perspective view of the locking rib. Fig. 8 is a fragmentary perspective view showing the manner of releasing the locking rib.

Referring now to the drawings in which like characters of reference designate similar parts, 10 designates the sash which is preferably formed of sheet metal. ln constructing each rail of the sash, the sheet metal is bent in the form of a U as shown, one leg being terminally formed with an inward y directed hook flange 11, and the other leg being terminally bent obliquely inwardly beyond the flange 11 as shown at 12, thence bl 111 inwardly and backwardly upon itself in the form of a rightangle as shown at 13,- the Patented Uct. 28,1913.

extreme end being bent back toward the inclined portion 12 to form a spring leaf 1 1. 7

Both side rails of the sash are formed with guide strip receiving depressions 15.

The abutment rib 16 is formed from a single length of sheet metal one edge of which is bent to form a hook flange 17 adapted to interlock withthe hook flange 11 of the rail, the material thence being bent to form a longitudinal 'rib 18 'of substantially circular cross section, and the other edge of the material being bent obliquely toward the rib as shown at 19, thence being terminally bent inwardly and backwardly in the form of a rightangle as shown at 20 which is adapted to fit within and snugly conform to the contour of the rightangular extremity 13 of the rail. The abutment rib thus bridges and secures together the legs of the rail.

The locking rib 21 is bent longitudinally at one edge to form a jaw 22 adapted to conform to the contour of one side of the rib 18, and is extended from this jaw in a straight portion 23 adapted to extend toward and contact with the rightangular portion 13 of the rail, and is thence bent back upon itself as shown atnlat to stiffen the portion 23, the stiffening "portion being terminally bent to form a curved spring jaw 25 which is adapted to conform to the contour of the opposite side of the rib 18 from the jaw 22, the jaw lhbeing thence bent terminally to form a hook-like flange 26 adapted-to enter the space between the spring leaf 14: of the rail and adjacent portion of the abutment rib and to bear against and clamp into this space a rod 27. v

When it is desired to secure a screen 28 in the sash, the marginal edges of the screen are inserted in the space between the spring leaf 14 of each rail and adjacent portion of the abutment rib 16 and the rod 27 then placed upon the screen as clearly shown in Fig. 2. The locking rib 21 is then applied by pressing the spring jaws 22 and 25 over the rib 18 whereupon the straight portion 23 of the locking rib bears upon and binds the screen against the rightangular portion 13 of the rail and the lioolrflange 26 of the locking rib bears against the rod 27 and prevents withdrawal of the screen.

hen it is desired to apply a window pane 29 to the sash the rods 27 are dispensed with, and, the marginal edges of the pane are placed upon the rightangular portions 13 of eaclrrail. The locking rib 16 is then applied by pressing the spring jaws over the rib 1S. whereupon the straight portion '23 ot the locking rib bears upon and binds the marginal edges of the pane against the rightangular portion 13 of the rail.

'i odetach the locking rib in order to substitute the screen for the Window pane or vice versa, it is simply necessary to insert the point of a screw-driver or other tool between the straight portion 13 of the riband window pane or screen as the case may be, then pry the straight portion outwardly, whereby the spring'jaivs expand and facilitate the locking rib being Withdrawn bodily outwardly. 7

What is claimed is l. A sash comprising channel metal rails connected together, a bridge melnber connecting the legs of each channel metal rail and having a longitudinal bead of substantially circular cross section, and a locking member having a straight portion adapted to clamp the marginal edge of a screen against one of said legs and terminating in spring jaws adapted to engage with said bead.

2. A sash comprising channel metal rails connected together, each rail having one leg terminating in a substantially rightangular abutment portion, a bridge member connecting said le s and having a longitudinal bead,

and a locking member having curved spring aws adapted to engage with said bead, and having a straight portion connectlng said jaws and extending obliquely along said edge bearing against said abutment portion,

a rod carried by said marginal edge and bearing against said bridge member, and a locking member having spring jaws engaging said longitudinal rib and having a por-, tion bearing against said rod and clamping the same against said bridge member, and having a portion between said clamping portion and said jaws bearing against said screen and clamping the same to said abutment portion.

In testimony whereof, I afiix my signature, in the presence of two Witnesses.
